OF NEW SOUTH WALES. 331 



Genus Lophoseris, M. Ed. Sf 5., 1849. 

 Corallum compound, adherent, foliaceous in crests or irregular 

 lobes, covered with radiate and coufluent calices ; columella 

 tuberculous and sometimes rudimentary ; the common surface 

 destitute of epitheca and finely striate. The very thin expansions 

 of this coral with calices on generally both sides distinguish it 

 from all the other Fungidse. 



Lophoseris cristata. Ellis fy ^olander. 



Corallum in a tuft of erect crested thin expansions with calices 

 on both surfaces ; the expansions are much thinner in the edges, 

 are raised and coalesce with, many vertical ridges ; calices cl >se, 

 and the septacostal rays elongated ; fossa distinct and somewhat 

 deep ; columella a little tubercle or absent ; septa in three cycles 

 the last wanting in one or two systems ; secondaries nearly 

 equalling primaries ; tertiary very thin all slightly toothed at the 

 edge and somewhat granular, principally developed vertically 

 though a little bent ; calices about 3 millim.

 Moreton Bay. 



LOPHOSERIS FRONDIFERA. Lamarck. 



This species has the calices a little smaller than the last, with 

 16 to 18 very thin septa, close, alternately exsert, and scarcely 

 serrated ; the corallum is very small. If I am correct in my 

 identification this is not very uncommon on the coasts of Queens- 

 land as far south of the tropics as Wide Bay. 



Second order, Madreporaria perforata. Corals formed almost 

 entirely of porous or reticulated coenenchyma ; septa very distinct 

 in character, composed primarily of six elements, but sometimes 

 represented by a series of little bars or processes ; transverse 

 divisions, rudimentary, never forming floors or tabulae ; the wall 

 which constitutes the greater portion is always perforated and 

 does not develope costal laminee ; visceral chamber open from 

 the base to the summit, and has neither traverses nor synap- 

 ticulae nor floors ; there are two divisions in this section: 1st, 

 Madreporidce ; mural system well developed and simply porous ;
